Hi!
anybody knows that where is set_user_nice() function called in the kernel? i couldn't find that. i just found that in forking operation do_fork()->copy_process()-> dup_task_struct() called then set_user_nice() called but i couldn't find that where. Also how/where do_fork() function called in kernel i couldn't find.
In x86, do_fork() is called from sys_fork()... check : http://lxr.linux.no/#linux+v3.1.1/arch/x86/kernel/process.c#L235 While sys_fork() itself, since it's a syscall handler, is called from entry.S. Please refer to: http://lxr.linux.no/#linux+v3.1.1/arch/x86/ia32/ia32entry.S#L475 -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
